EDAC: Properly unwind on failure path in edac_init()
edac_init() does not deallocate already allocated resources on failure path. Found by Linux Driver Verification project (linuxtesting.org). [ Boris: The unwind path functions have __exit annotation but are being used in an __init function, leading to section mismatches. Drop the section annotation and make them normal functions. ] Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru> Link: http://lkml.kernel.org/r/1423203162-26368-1-git-send-email-khoroshilov@ispras.ru Signed-off-by: Borislav Petkov <bp@suse.de>
